Christmas in New Zealand is typically celebrated on December 25th, just like in other parts of the world. However, because it's summer in New Zealand at this time of year, the holiday is often celebrated with a more relaxed, beachy vibe. Many families and friends gather together for a barbecue, a swim in the ocean, or a picnic in the park. It's also common to see decorations like Christmas trees and lights throughout the city, even though the weather is warm and sunny.
